NOTE TO READERS: When this project lost substantial funding at the end of 2018, I lost the ability to continue publishing criteria-driven news story reviews and PR news release reviews - once the bread-and-butter of the site going back to 2006. The 3,200 archived reviews, while still educational, are getting old and difficult for me to technically maintain on the back end of the website. So I am announcing that I plan to remove these reviews from the site by April 1, 2021. The blog and the toolkit - two of the most popular features on the site - will remain. If you wish to peruse the reviews before they disappear, please do so by the end of March 2021. After that date you may still be able to access them via the Internet Archive Wayback Machine -

Prevention magazine: we're watching you

Posted By


Last week I wrote about one instance of Prevention magazine using inaccurate language to describe an observational study. Today I found more examples in the May issue – this time inaccurate language used repeatedly in one article, “12 Power Health Moves.”

It tells readers they can “lower risk of dementia 19%” if they “serve fish tonight.”
Or they can “live five years longer” if they “sip some Merlot.”
Or the 400% drop in risk of head and neck cancer by brushing and flossing.

Each of these blurbs came from observational studies, from which you can’t prove cause and effect. Therefore it is simply inaccurate to say you can “lower risk” or “live longer” based on this kind of evidence.

The MSN health and fitness site republished a form of the Prevention article – although with some of the hyperbole stripped away.

I don’t normally see Prevention magazine. I had one of those use-them-or-lose-them frequent flyer point deals where I could subscribe to magazines instead of just throwing the points away. So, Prevention, we’re watching you.
